1) The lens is made of the finest quality optical glass giving crystal clear view with the object being seen in its true natural colours. 2) This 4X area magnification lens has a large rectangular
size (170 mm X 105 mm) specially designed for giving perfectly strainfree vision with both eyes. This enables continuous viewing for long hours without any fatigue whatsoever. 3) The entire spring
balancing mechanism of the magnifier is built inside the magnifier's body, thus providing some unique advantages: a) Most pleasing form and aesthetics. b) This unbroken external surface can be
provided with highly durable surface finish, thus ensuring that the unit retains its aesthetic appeal even after several years of heavy duty usage. c) Also, because of this enclosed construction
this model is the ideal choice for use in highly corrosive or humid environment. 4) This model's enclosed construction is particularly amenable to Electro Static Discharge (ESD) Proofing, which is
mandatory in certain sensitive applications such as in electronics and explosives industries. 5) This model offers both shadowless as well as directional lighting modes. Although in general
shadowless illumination is preferred - there are many applications (eg. study of minute surface defects) where directional illumination is essential for highlighting defects and other features of
interest. 6) Since the lens is held in a slim (but tough) edge from the front side, the user does not lose eye-contact with the object under view when switching between direct and magnified view.
